The update that happened in April took out my Sim and lost network for good. Not even a hardened Sim would help my poor A54. I guess all is well I was accommodated with an upgrade after 3 weeks of no network. I will forever be Samsung . I've been team Samsung since the j3 and 😅
Just one man's opinion. I highly doubt the update alone took out your sim. I would tend to believe there was something else on their phone whether it was malicious or not, that interfered/reacted with the update causing it to corrupt your sim card.
@LCMorgan00 Did you wipe the device cache partition after the update? I recommend that you do this after every device update. It wipes out incompatible or outdated cache information which might be incompatible after the update. It does not erase any user data nor applications.
To wipe the device cache partition:
1. Power off your device. 2. Power up while holding down the Volume up key and the Side key until the Samsung logo appears. 3. An Android recovery menu will appear. 4. Use the Volume down key to scroll down to Wipe cache partition. 5. Click the side key to select it. 6. Use the Volume down key to scroll down to Yes. 7. Click the side key to select it. The Cache will be wiped almost instantaneously. 8. Click the side key to select "Reboot system now"
